摘要

The invention provides a process for the determination of the make-up torque to be applied on a joint for pipe, destined to the petroleum industry according to which a reference mark is set on the male element and on the female element, so that when the two reference marks are brought to face each other, the make-up restriction stops (2) on the male element (1) and on the female element come into contact with each other; that after having applied a grease, we proceed to make-up by applying sufficient torque to cause one element to rotate with respect to the other one, at a predetermined angle beyond the point where the reference marks are facing each other, and we proceed to measure the torque; that this operation is repeated on a sufficient number of joints; and that a determination is made of the range of torques to be applied on the joints of this type with the grease that has been used.
